I have next two servers:
Solaris 8, Oracle 8.1.7, SAP 46C installed and working for production
Solaris 10, Oracle 10 with NO SAP but with 40% more of the capacity than previous server
I will install and configure SAP ECC 6.0 in ServerTo and will transfer all data from 46C. Under this scenario I would like to know if the next generic steps are valid:
Homogeneous copy of SAP 46C using r3copy
Begin installation of SAP ECC 6.0
In some phase of the installation, I expect SAP asks for the copy generated in step 1.
Continue with the installation, I am supposing that ECC 6.0 will be able to recognize that the copy files generated in step 1 correspond to SAP 46C version and will import data transparently.
I configure SAP ECC 6.0 and apply last patches.
At the end, I will have two productive SAPs in different versions.
Update: You comment( if I read it correctly) sounds like a working solution. Here are, what I think, the usual steps. You should do them first on a test system. Just to put some perspective. We did this upgrade recently ( from 4.6c to ecc6) during the project we did something between 10 to 15 upgrades on testing, integration an training systems.
Before update: I think that you are to optimistic. The sap upgrade process is anything but simple.
